| 摘 要： | 鉴于世界坐标系定义的空间往往远大于被描绘物体的几何尺寸、导致了数据冗余、分辨率低。提出用物体坐标系表示三维图形，使存储空间减小，分辨率提高，并可提高运算速度。

| Abstract: | The world coordinates' scope is much bigger then the object of been represented.This lead to larger redundancy and lower resolving power.Set forth the representations of three-dimensional object by object coordinates.It can reduce redundancy and provide higher resolving power and speed. |
| |
| Keywords: | three-dimensional object coordinates directed acycline graph(DAG) |
